Thank you for purchasing the MegaRAID

1078-based PCI-

Express SAS (Serial Attached SCSI/Serial ATA II) 8880EM2

RAID Controller.

Please take a few minutes to read this quick installation

guide before you install your RAID controller. If you need

more information about any topic covered in this guide, refer

to the related documents on your MegaRAID Universal

Software Suite CD.

Note: SATA II is the only type of SATA supported by this

RAID controller.

You can connect the LSI intelligent Battery Backup Unit 07

(LSIiBBU07) directly to the SAS 8880EM2 RAID Controller.

For more information about this battery, refer to the

Intelligent Battery Backup Unit for 1078-based MegaRAID

Products User’s Guide on the MegaRAID Universal Software

Suite CD.

RAID CONTROLLER INSTALLATION

Step 1 Unpack the RAID Controller

Unpack the MegaRAID SAS 8880EM2 RAID

Controller in a static-free environment. Remove it

from the antistatic bag, and inspect it for damage.

If the RAID controller appears to be damaged, or

if the MegaRAID Universal Software Suite CD is

missing, contact LSI or your MegaRAID OEM

support representative.

The CD contains utility programs, device drivers

for various operating systems, and the following

documentation:

• MegaRAID 1078-based SAS RAID Controllers

User’s Guide

• MegaRAID SAS Software User’s Guide

• MegaRAID SAS Device Driver Installation

User’s Guide

• Intelligent Battery Backup Unit for 1078-based

MegaRAID Products User’s Guide

• Software license agreement

Step 2 Prepare the Computer

Turn off the computer, and unplug the power

cords from the rear of the power supply. Remove

the cover from the computer.

Step 3 Review the Jumpers and the Connectors

Figure 1 shows the location of the jumpers and

the connectors on the SAS 8880EM2 RAID

Controller. The jumpers are set at the factory, and

you usually do not need to change them.

Back up your data before you change your

system configuration. Otherwise, you might lose

data.

CAUT ION

Before you install the RAID controller, make sure

that the computer is disconnected from the power

and from any networks.

Step 4 Install the RAID Controller

Insert the RAID controller in a PCI Express slot

on the motherboard, as shown in Figure 2. Press

down gently, but firmly, to seat the card correctly

in the slot. Secure the RAID controller to the

computer chassis with the bracket screw.

Note: Refer to the guide for your motherboard for

information about the PCI Express slot.

Note: This is a PCI Express x8 card. It can operate in

x8 or x16 slots.

Step 5 Configure and Install the SAS Devices, SATA

II Devices, or Both in the Host Computer Case

Refer to the documentation for the devices for any

preinstallation configuration requirements.

Step 6 Connect the MegaRAID SAS 8880EM2 RAID

Controller to the Devices

Use SAS cables to connect the SAS RAID

controller to SAS devices, SATA II devices, or

both. See Figure 1 to view the connector

locations on the RAID controller.

Refer to the MegaRAID 1078 SAS RAID

Controllers User’s Guide on the MegaRAID

Universal Software Suite CD for detailed

information about the SAS cables.

Jumper/

Connector Type Description

J1 Battery Backup

Connector

20-pin connector

tery backup unit. The LSIiBBU07

connects directly to the SAS

8880EM2 RAID Controller.

J2 Universal Asyn-

chronous Receiver/

Transmitter

debugging

4-pin connector

Reserved for LSI use.

1. Note: This connector uses

3.3V LVTTL levels and will be

damaged if connected to stan-

dard transceiver levels.

J5 BIOS Disable 2-pin connector

Reserved for LSI use.

J6 Board Default

Debug

2-pin connector

Reserved for LSI use (default

jumper).

Step 7 Turn on the Power to the Computer

Reinstall the computer cover, and reconnect the

power cords. Turn on the power to the computer.

Make sure that the power is turned on to the SAS

devices and the SATA II devices before or at the

same time that the power to the host computer is

turned on. If the power is turned on to the

computer before it is turned on to the devices, the

computer might not recognize the devices.

The firmware takes several seconds to initialize.

During this time, the RAID controller scans the

ports.

Step 8 Run the WebBIOS Configuration Utility

Run the WebBIOS Configuration Utility to

configure the physical arrays and the logical

drives. When the message Press <Ctrl><H> for

WebBIOS appears on the screen, immediately

press CTRL+H to run the utility.

Note: Refer to the MegaRAID SAS Software User’s

Guide on the MegaRAID Universal Software

Suite CD for detailed steps on configuring

physical arrays and logical drives.

Step 9 Install the Operating System Driver

The RAID controller can operate under various

operating systems, but you must install the

software drivers first.

The MegaRAID Universal Software Suite CD

includes the software drivers for the supported

operating systems, along with documentation.

You can view the supported operating systems

and download the latest drivers for RAID

controllers on the LSI Logic web site at: http://

www.lsi.com/cm/DownloadSearch.do. Access the

download center, and follow the steps to

download the driver.

Refer to the MegaRAID SAS Device Driver

Installation User’s Guide on the MegaRAID

Universal Software Suite CD for details on

installing the driver. Be sure to use the latest

service packs that are provided by the operating

system manufacturer and to review the readme

file that accompanies the driver.

SUPPORTED RAID LEVELS

The SAS 8880EM2 RAID Controller support disk arrays

using the following RAID levels:

• RAID 0 (data striping): Data is striped across all disks in

the array, enabling very fast data throughput. There is no

data redundancy. All data is lost if any disk fails.

• RAID 1 (disk mirroring): Data is written simultaneously

to two disks, providing complete data redundancy if one

disk fails. The maximum array capacity is equal to the

available size of the smaller of the two hard drives.

• RAID 5 (disk striping with distributed parity): Data is

striped across all disks in the array. Part of the capacity

of each disk stores parity information that reconstructs

data if a disk fails. RAID 5 provides good data throughput

for applications with high read request rates.

• RAID 6 (disk striping with distributed parity across

two disks): Data is striped across all disks in the array

and two parity disks are used to provide protection

against the failure of up to two physical disks. In each row

of data blocks, two sets of parity data are stored.

• RAID 10 (RAID 1 and RAID 0 in spanned arrays): RAID

10 uses mirrored pairs of disks to provide complete data

redundancy. RAID 10 provides high data throughput

rates.

• RAID 50 (RAID 5 and RAID 0 in spanned arrays): RAID

50 uses both parity and disk striping across multiple disks

to provide complete data redundancy. RAID 50 provides

high data throughput rates.

• RAID 60 (RAID 6 and RAID 0 in spanned arrays): RAID

60 uses both distributed parity across two parity disks and

disk striping across multiple disks to provide complete

data redundancy. RAID 60 provides high fault tolerance.
